Can you have 43 chromosomes?

Chromosomal mosaicism occurs from an error in cell division in cells other than eggs and sperm. Most commonly, some cells end up with one extra or missing chromosome (for a total of 45 or 47 chromosomes per cell), while other cells have the usual 46 chromosomes.

How many chromosomes are in a animal?

Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39. How many chromosomes do humans have?

Can you live without a chromosome?

Yes, but there are usually associated health problems. The only case where a missing chromosome is tolerated is when an X or a Y chromosome is missing. This condition, called Turner syndrome or XO, affects about 1 out of every 2,500 females. XO is one of the most common chromosomal abnormalities.

Do any humans have 48 chromosomes?

XXYY syndrome is a sex chromosome anomaly in which males have an extra X and Y chromosome. … Males with XXYY syndrome have 48 chromosomes instead of the typical 46. This is why XXYY syndrome is sometimes written as 48,XXYY syndrome or 48,XXYY. It affects an estimated one in every 18,000–40,000 male births.
